Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of transformer production equipment, specifically an automatic wax-soaking equipment for transformers. Background Technology
[0002] In transformer manufacturing, wax impregnation is a crucial process, aimed at improving the transformer's insulation and moisture resistance. Currently, factories using this method employ semi-open, manual equipment. The process involves an employee removing a tray of material from the oven and placing it in a fixture. The screw is then turned to adjust the height, immersing the material in the wax solution. After three minutes of impregnation, the material is removed and placed above the wax furnace to allow the wax to solidify before proceeding to the next process.
[0003] This method has the following drawbacks: 1) The melted wax in the wax furnace has an irritating smell, and prolonged inhalation is harmful to the health of employees; 2) The entire tray of material, including the iron tray, weighs about 10KG, which is difficult for employees to handle and may cause work-related injuries; 3) It is impossible to effectively control the depth of wax immersion, and relying on manual control is extremely unstable, leading to fluctuations in product quality; 4) Too many handling actions result in low efficiency and affect the production cycle.
[0004] Therefore, developing a transformer waxing equipment that can automate the waxing process is of great significance. It can effectively solve the problems existing in the current technology, improve work efficiency, reduce the intensity of manual operation, protect the health of employees, and improve the consistency of product quality.

The workbench 2 is equipped with a material handling fixture 3, a transverse material transfer mechanism 4, a longitudinal material transfer mechanism 5, a magnetic material transfer component 6, a wax furnace 7, a wax tank 8, a lifting mechanism 9, and a material discharge device 10.
[0039] The chassis 1, serving as the supporting frame for the entire equipment, is constructed from welded steel, with a surface treated for corrosion resistance and powder coating, providing excellent strength and durability. Chassis 1 is equipped with 12 casters at its bottom, each equipped with a locking device to ensure stable operation after the equipment is positioned. Inside chassis 1 is an electrical control cabinet for housing PLC controllers, frequency converters, relays, and other electrical components, and is equipped with cooling fans to maintain the normal operating temperature of these components. A touchscreen is also located on the outer surface of chassis 1, supporting multi-touch operation. The interface is intuitive and user-friendly, allowing operators to easily set process parameters, monitor equipment status, and view alarm information.
[0040] The workbench 2 is mounted on the upper part of the chassis 1. It is made of steel plate and the surface has been precision machined to ensure flatness. The workbench 2 is equipped with multiple T-slots to facilitate the installation and adjustment of various functional components.
[0041] The material handling fixture 3 is installed on the upper left of the workbench 2 to receive the transformer material flowing in from the previous process. The material handling fixture 3 is made of high-strength aluminum alloy with an anodized surface, providing excellent wear resistance and corrosion resistance. The material handling fixture 3 is also equipped with a position sensor; when the transformer material reaches the designated position, the sensor sends a signal to the PLC controller, triggering subsequent automated operations.
[0042] The transverse transfer mechanism 4 is mounted above and behind the worktable 2, providing linear motion in the X-axis direction. The transverse transfer mechanism 4 includes a transverse slide rail, a transverse slider mounted on the transverse slide rail, and a transverse drive motor that drives the transverse slider to slide left and right along the transverse slide rail. The transverse slide rail is a high-precision linear guide, possessing high rigidity and high precision characteristics, and can withstand large loads. The transverse slider is a slider matched to the slide rail, with built-in circulating balls, resulting in a low coefficient of friction and smooth movement. The transverse drive motor is a servo motor, driving the transverse slider to slide left and right along the transverse slide rail via a synchronous pulley and rack. This transmission method features high precision, high rigidity, and low backlash, meeting the requirements of precise wax coating processes.
[0043] The longitudinal transfer mechanism 5 is mounted on the transverse slider, providing linear motion in the Y-axis direction.

The electromagnet is controlled by a PLC controller to achieve precise attraction and release of the transformer materials. Compared to traditional mechanical clamping devices, the magnetic method is faster, more reliable, and does not damage the surface of the transformer materials.
[0045] The workbench 2 has mounting holes through which the wax furnace 7 is installed. The wax furnace 7 is equipped with a heating element. The wax furnace 7 is made of stainless steel, possessing excellent corrosion resistance and high-temperature resistance. An insulation layer made of aluminum silicate fiber is installed on the outside of the wax furnace 7, with a thermal conductivity of less than 0.05 W / (m·K), effectively reducing heat loss, maintaining temperature stability within the wax furnace 7, and improving energy efficiency. A temperature sensor, a PT100 platinum resistance temperature sensor, is also installed inside the wax furnace 7 to monitor the temperature in real time and adjust it via a PLC controller, ensuring the wax is maintained at the optimal working temperature and guaranteeing the quality of the wax bath. The upper part of the wax furnace 7 is flush with the workbench 2, facilitating the precise positioning of the transformer material above the wax furnace 7 by the cooperation of the transverse material transfer mechanism 4 and the longitudinal material transfer mechanism 5.
[0046] The wax tank 8 is located inside the wax furnace 7. The wax tank 8 is also made of stainless steel. The wax tank 8 has lifting lugs on both sides for connecting the lifting mechanism 9.
[0047] Lifting mechanisms 9 are installed on both sides of the wax furnace 7 to drive the wax tank 8 to move up and down. Lifting mechanism 9 includes lifting guide rods and a lifting motor that drives the lifting guide rods to move up and down. The lifting guide rods are made of stainless steel with a hard chrome finish, providing excellent wear resistance and corrosion resistance. The upper end of the lifting guide rod connects to both sides of the wax tank 8, and the lower end connects to the output end of the lifting motor. The lifting motor is a servo motor that drives the lifting guide rods up and down through a precision ball screw transmission mechanism. This innovative design uses a lifting method for the wax tank 8 instead of the traditional material descent method. Through precise control of the lifting motor, the wax tank 8 can be raised and lowered to a preset, precise position, ensuring that the immersion depth of the wax is completely consistent each time.
[0048] The discharge device 10 is installed on the right side of the workbench 2 and is used to transport the wax-coated transformer material. The discharge device 10 includes a conveyor track, a conveyor slide mounted on the conveyor track, a conveyor motor that drives the conveyor slide to slide along the conveyor track, and a discharge fixture 11 mounted on the conveyor slide. The conveyor track is made of aluminum alloy profile with an anodized surface, providing good wear resistance and corrosion resistance. The conveyor slide is made of high-strength engineering plastic material, is lightweight, and has low inertia. The conveyor motor is a stepper motor, which drives the conveyor slide to slide along the conveyor track via a synchronous belt drive mechanism, ensuring smooth operation and accurate positioning. The discharge fixture 11, mounted on the conveyor slide, is used to support the wax-coated transformer material. Its design takes into account the shape characteristics of the transformer material, ensuring that the material can be placed stably.
[0049] The PLC controller is the core of the entire equipment's control system, employing a Siemens S7-1200 series PLC, which boasts high reliability and powerful processing capabilities. Through programming, the PLC controller precisely controls and coordinates the transverse material transfer mechanism 4, the longitudinal material transfer mechanism 5, the magnetic material transfer assembly 6, and the lifting mechanism 9, ensuring that each mechanism operates according to predetermined timing and parameters. The PLC controller also receives signals from various sensors, such as temperature and position sensors, and makes corresponding control adjustments based on these signals to guarantee the safe and stable operation of the equipment.
[0050] The PLC controller can be programmed with various process parameters, including wax soaking time, wax soaking depth, and wax furnace temperature. These parameters can be adjusted via a touchscreen to meet the wax soaking requirements of transformers of different specifications. This flexible parameter setting capability enables the equipment to adapt to the production needs of various transformer models, improving its versatility and adaptability.
[0051] The working process of this utility model is as follows:

Initialization and Equipment Preparation: The operator clicks the reset button on the touch screen, and the equipment enters the reset state; all mechanisms of the equipment return to their initial positions, and the touch screen displays the reset completion information; the operator clicks the external start button, and the equipment enters the running state, and the wax furnace 7 begins to heat to the working temperature.
[0053] 2. Receive materials from the previous process: Wait for the previous process equipment to deliver the transformer material to position 3 of the material handling fixture; the PLC controller receives the arrival signal from the previous process equipment; the system automatically starts the material handling program.
[0054] 3. Material Retrieval Stage: The PLC controller starts the horizontal drive motor of the horizontal transfer mechanism 4, which drives the synchronous wheel to drive the horizontal slider to the preset material retrieval position through the rack and pinion; the vertical drive motor of the vertical transfer mechanism 5 starts, which drives the vertical slider to the preset material retrieval height position; the PLC controller controls the magnet of the magnetic transfer component 6 to be energized, which attracts the transformer material; the vertical transfer mechanism 5 is raised to a safe height, completing the material retrieval action.
[0055] 4. Move to the wax soaking position: The horizontal drive motor of the horizontal material transfer mechanism 4 starts, driving the transformer material to the preset wax soaking position above the wax furnace 7; after reaching the preset position, the horizontal drive motor stops running, ready to carry out the wax soaking operation.
[0056] 5. Wax soaking operation: The PLC controller starts the lifting motor of the lifting mechanism 9, driving the lifting guide rod to raise the wax tank 8 from the wax furnace 7 to the preset working height; the longitudinal drive motor of the longitudinal material transfer mechanism 5 starts, driving the transformer material down to the preset wax soaking depth position; after reaching the set position, the system maintains this state, and the timer starts timing; the temperature sensor monitors the temperature of the wax furnace 7 in real time to ensure that the temperature is stable during the wax soaking process; after the preset wax soaking time ends, the longitudinal material transfer mechanism 5 drives the transformer material to rise and leave the wax; it hovers above the transformer material for a moment to allow excess wax to flow back to the wax tank 8; the lifting motor of the lifting mechanism 9 reverses, lowering the wax tank 8 back into the wax furnace 7, completing the wax soaking operation.
[0057] 6.

[0059] Throughout the operation, the PLC controller monitors the signals from various sensors and the status of the mechanisms in real time to ensure the safe and stable operation of the equipment. In case of abnormalities, such as abnormal temperature, motor overload, or cylinder failure, the system will automatically stop and issue an alarm to prompt the operator to handle the situation.
[0060] The automatic wax-soaking equipment for transformers of this utility model demonstrates many technical advantages in practical applications:
[0061] First, the equipment employs a material transfer system (lateral transfer mechanism 4, longitudinal transfer mechanism 5, and magnetic transfer assembly 6) to achieve precise positioning and handling of transformer materials. The lateral transfer mechanism 4 provides movement along the X-axis, covering the entire working range from the material pick-up position to the material discharge position; the longitudinal transfer mechanism 5 provides movement along the Y-axis, adapting to different height operating requirements; and the magnetic transfer assembly 6 is used to pick up the transformer materials, ensuring precise positioning of the materials to the wax-coated position. These three mechanisms work together to form a complete material transfer system with high positioning accuracy, far superior to that of manual operation.
[0062] Secondly, the equipment innovatively employs a lifting mechanism for the wax tank 8 during the wax soaking process. Traditional wax soaking equipment typically lowers the transformer material into a fixed position in the wax tank 8. This method makes it difficult to precisely control the immersion depth and is prone to damaging the transformer material due to improper operation. This equipment, however, uses a lifting mechanism 9 to drive the wax tank 8 to a preset height, keeping the transformer material in a fixed position. This design not only allows for precise control of the immersion depth but also avoids quality problems caused by shaking during the material's descent. The lifting mechanism 9 is driven by a servo motor, ensuring smooth operation and accurate positioning, thus guaranteeing consistency in each wax soaking process.
[0063] Third, the magnetic material transfer component 6 of the equipment adopts a controllable electromagnet design, which can stably adsorb transformer materials. Furthermore, the PLC controller precisely controls the power supply to achieve accurate adsorption and release of the materials. This design not only simplifies operation but also avoids potential damage to the transformer material surface caused by mechanical clamps, thus improving product quality.
[0064] Fourth, the equipment's temperature control system is precisely designed. The insulation layer on the outside of the wax furnace 7 effectively reduces heat loss and improves energy efficiency. The built-in PT100 platinum resistance temperature sensor monitors the temperature of the wax furnace 7 in real time, ensuring that the wax temperature is always maintained within the optimal operating range. The temperature signal is fed back to the PLC controller, which controls the on / off state of the heating elements to achieve precise temperature control, which is crucial for ensuring the quality of the wax bath.
[0065] Fifth, the equipment boasts a high degree of automation. The entire wax-soaking process, from material handling and movement to wax soaking and discharge, is automatically completed by the PLC controller, requiring no manual intervention. The PLC controller uses the Siemens S7-1200 series, possessing powerful processing capabilities and high reliability, enabling precise control of the operating sequence and parameters of each mechanism. The touchscreen interface is intuitive and user-friendly, allowing operators to master equipment operation with minimal training, significantly reducing operational difficulty and the possibility of human error.
[0066] Sixth, the equipment features comprehensive safety design, including multiple safety protection measures. For example, the equipment is equipped with an emergency stop button to immediately cut off the power in case of abnormalities; each moving mechanism has limit switches and overload protection devices to prevent mechanical damage caused by misoperation; the wax furnace 7 has an over-temperature protection device that automatically cuts off the heating power when the temperature exceeds the set upper limit to prevent fire risks; the PLC control system has a self-diagnostic function, which can promptly detect and report system faults. These safety measures ensure the safe operation of the equipment under various working conditions.
[0067] Seventh, the equipment is easy to maintain, with all major components adopting a modular design for easy repair and replacement. For example, the transverse material transfer mechanism 4 and the longitudinal material transfer mechanism 5 use standard linear guides and sliders, and replacement parts are readily available on the market; the components in the electrical control cabinet are installed using standard DIN rails, facilitating inspection and replacement; the software system is designed with a remote diagnostic interface, allowing technicians to remotely view the equipment status and fault information via the network and provide timely technical support.
[0068] In summary, this utility model's automatic transformer wax-soaking equipment, through innovative structural design and control technology, achieves full automation of the transformer wax-soaking process, significantly improving work efficiency, enhancing the working environment, and ensuring consistent wax-soaking quality. Compared to traditional manual wax-soaking equipment, this equipment offers significant advantages in efficiency, quality, safety, and user-friendly design, providing transformer manufacturers with an ideal wax-soaking solution.
